Answer:
3 nickels and 5 quarters
Step-by-step explanation:
Let n = number of nickels
q = number of quarters
q = n+2
.25q + .05n = 1.40
Using the first equation and replacing q in the second equation
.25( n+2) + .05n = 1.40
Distribute
.25n+.50 +.05n = 1.40
Combine like terms
.30n +.5 = 1.40
Subtract .5 from each side
.3n +.5-.5 = 1.40-.4
.3n = .9
Divide by .3
.3n/.3 = .9/.3
n = 3
q = n+2
q=5
Step-by-step explanation:
Let the
Nickel coin = x
Quarter coin = y
y = n + 2
0.25y + 0.05x = 1.4
0.25(x + 2) + 0.05x = 1.4
0.25x + 0.5 + 0.05x = 1.4
0.25x + 0.05x = 1.4 - 0.5
0.30x = 0.9
x = 0.9/0.3
x = 3
y = 3 + 2 = 5
Find 4x when x= 3.

Answer:
Refer the attached graph.
Step-by-step explanation:
Step-by-step explanation:
Given : Equation
To find : What is the graph of the equation ?
Solution :
To plot the graph of the equation we have to determine the x and y-intercept of the equation as is a linear equation.
For x-intercept, put y=0
Point is (1,0).
For y-intercept, put x=0
Point is (0,-2).
So, The graph passing through (1,0) and (0,-2) with linear line.

The number of foxes in national Forest has grown by 770 in the past year if the number of foxes at the beginning of the year was 5500 by what percent did it increase
Answer:
14%
Step-by-step explanation:
Divide 770 by 5500.
You get 7/50 or 0.14.
When you convert that to a percentage, you get 14%
Based on the information given, the percentage increase will be 14%.
From the information given, it was stated that the number of foxes in national Forest has grown by 770 in the past year and that the number of foxes at the beginning of the year was 5500.
The percentage increase will be:
= 770/5500 × 100.
= 0.14 × 100
= 14%

Solve for x 4(x + 2) = 3 (x - 2)
Answer:
x = -14
)Step-by-step explanation:
To find the value of x
Transpose
4(x + 2) = 3 (x - 2)
4x + 8 = 3x - 6
4x - 3x = -6 -8
x = -14
we can even cross check
putting the value of x by -14
4(x + 2) = 3 (x - 2)
4 (-14 +2) = 3 (-14 -2)
-56 +8 = -42 -6
-48 = -48
same = same
so CROSS-CHECKED
Answer:
x = -14
Step-by-step explanation:
4(x + 2) = 3 (x - 2)
4x + 8 = 3x - 6
x + 8 = -6
x = -14

How do you convert 0.580 (80repeating) as a fraction?
Answer:
58/100
Step-by-step explanation:
9514 1404 393
Answer:
115/198
Step-by-step explanation:
The repeat is 2 digits, so you can multiply the number by 10 to that power.
x = 0.58080...(2-digit repeat)
100x = 58.08080...(2-digit repeat)
Then subtract the original number.
100x -x = 99x = 58.08080... -0.58080... = 57.5
Now, divide by the coefficient of x.
x = 57.5/99 = 115/198
This fraction cannot be reduced, so is the fraction you're looking for.
0.580...(2-digit repeat) = 115/198
_____
Additional comment
The number of 9s in the denominator is the number of repeating digits. If the repeat started at the decimal point, the fraction would be those two repeating digits divided by two 9s (99).
Your number can be considered to be ...
0.58080...(2-digit repeat) = 0.5 + 0.0808...(2-digit repeat)
This will be ...
0.58080... = 1/2 + 8/99 = 99/198 +16/198 = 115/198
The distance from the earth to the moon is two hundred thirty eight thousand, nine hundred miles. Write the distance in standard form and expanded form.
Answer:
Standard: 238,900
Expanded: 200,000 + 30,000 + 8,000 + 900
Step-by-step explanation:
The distance in standard form is 238,900 and in expanded form is 200,000 + 30,000 + 8,000 + 900.
What is an expression?Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
Given that the distance from the earth to the moon is two hundred thirty-eight thousand, nine hundred miles.
The number in standard form will be written as below:-
Standard form = 238,900
The number in the expanded form will be written as below:-
Expanded form = 200,000 + 30,000 + 8,000 + 900.
Therefore, the distance in standard form is 238,900 and in expanded form is 200,000 + 30,000 + 8,000 + 900.

which reflection carries parallelogram QRST onto itself?
Step-by-step explanation:
that 180° and 360° clockwise and counterclockwise rotations about this point will carry the parallelogram onto itself.
The parallelogram forms the angle [tex]180[/tex] degree and [tex]360[/tex] degree.
What is the parallelogram?
A parallelogram is a flat shape with four straight, connected sides so that opposite sides are congruent and parallel.
This means a parallelogram is a plane figure, a closed shape, and a quadrilateral.
If we rotate it in clockwise then it covers the angle [tex]180[/tex] degree and [tex]360[/tex] degree whether it is in clockwise or in anticlockwise.
Hence, the parallelogram forms the angle [tex]180[/tex] degree and [tex]360[/tex] degree.

a) Find the slope of the curve y= x^3 + 3 at the point P(-2, -5)
b) Find an equation of the tangent line to the curve at P(-2, -5)
9514 1404 393
Answer:
a) 12
b) y +5 = 12(x +2)
Step-by-step explanation:
The slope of a function is its derivative.
a) The slope of y = x^3 +3 at any point is y' = 3x^2. So, at the point where x=-2, the slope of the curve is ...
m = 3(-2)^2 = 12 . . . . slope at (-2, -5)
__
b) The equation of the tangent line is most easily written using the point-slope form of the equation of a line.
y -k = m(x -h) . . . . . line with slope m through point (h, k)
y +5 = 12(x +2) . . . . line with slope 12 through point (-2, -5)
